A 2,000W pure sine wave inverter covers the vast majority of what van lifers and RV users want to run from battery. Here's exactly what fits, what's borderline, and what won't work.

For inverter sizing in general: what size inverter do I need?. For installation: how to install an inverter in a van or RV.

What a 2,000W inverter runs easily

These all draw well under 2,000W and a 2,000W inverter handles them without strain:

ApplianceTypical wattsNotes
Laptop (charging)45–90WEssentially zero impact
Phone charging5–25WNegligible
Tablet10–30WNegligible
LED TV (24–32")30–80WFine
CPAP (no heat)30–60WFine; pure sine required
Electric blanket100–200WFine
Small fan20–50WFine
Drip coffee maker600–1,200WFine for a 10-minute brew
Single-serve coffee (Keurig/Nespresso)1,200–1,500WFine for 1–2 minute brew
Blender300–600WFine
Toaster800–1,200WFine for a few minutes
Induction cooktop (medium setting)600–1,200WFine; use a 2,000W inverter for headroom
Hair dryer (low heat)500–900WFine on low; high setting may hit limits

What's at the limit

These loads are technically within a 2,000W continuous rating but push the inverter and require a good battery bank:

ApplianceTypical wattsReality check
Induction cooktop (max setting)1,500–1,800WLeaves little headroom; use nothing else simultaneously
Hair dryer (high heat)1,500–1,800WSame — nothing else running
Small portable air conditioner (5,000 BTU)450–600W running, 1,500–2,000W startup surgeThe surge is the issue; needs a high-surge inverter
Small electric space heater750–1,500WWorks but drains the battery very fast

What a 2,000W inverter won't run

ApplianceWhy not
Full-size RV rooftop AC (13,500 BTU)1,200–1,800W running + 3,000–6,000W startup surge — exceeds a 2,000W inverter
Electric water heater1,500–4,500W continuous — possible at low wattage but impractical
Full-size microwave (1,000W+ cooking power)Draws 1,500–1,800W from the wall — right at the limit with nothing else running
Electric dryer4,000–6,000W — not a van appliance

The battery matters more than the inverter

A 2,000W inverter can only deliver what the battery can supply. At 2,000W output with 85% efficiency, the inverter draws ~2,350W (196A) from a 12V battery. A 200Ah LiFePO4 bank at that draw rate would last less than an hour.

In practice:

  • Cooking: 20 minutes at 1,500W = 500Wh — your 200Ah bank handles this easily and refills from solar
  • Coffee: 10 minutes at 1,200W = 200Wh — trivial
  • Laptop all day: 60W × 8 hours = 480Wh — easily covered

Van inverter use is almost always brief, high-watt bursts rather than sustained high-draw loads. A 200Ah LiFePO4 bank paired with 200–400W of solar handles typical van inverter use without issue.

Surge vs continuous rating

Most inverters are rated for both continuous watts and surge watts (typically 2× the continuous for a few seconds). Appliances with motors — blenders, AC units, some power tools — have a high startup surge that can exceed their running wattage.

A 2,000W continuous / 4,000W surge inverter can handle a small AC unit's startup even though the running load is under 2,000W. Check the surge rating before assuming an inverter can start a motor-driven load.

  • Renogy 2000W Pure Sine (~$200) — the value pick; widely used in van builds
  • Victron Phoenix 12/2000 (~$500) — premium quality, Victron ecosystem integration
  • Victron MultiPlus 12/2000 (~$650) — if you want built-in shore power charging too
